Abstract (en)

[origin: EP3907253A1] The present disclosure relates to a super absorbent polymer composition. More specifically, the present disclosure relates to a super absorbent polymer composition prepared such that agglomeration between polymer particles is suppressed by including an additive having a specific structure, and thus an additional pulverizing process is not required after drying.
